Is this reproducible with the latest release available on Maverick?

Happens for me with one DVD, seems to be a fault situation that also segfaults k9copy, though K3b and VLC can both read the DVD OK-ish.
My suspicion is either a read error or copy protection trick that is causing the error, and these packages are not doing some sensibility check on what is read.
